Features
Pros
- ✓The suspended mesh back is the whole pitch, and it delivers — hot-climate hikers report dramatically drier shirts than any foam-back pack.
- ✓An included raincover at $160 beats the Talon's bring-your-own approach.
- ✓The perimeter frame transfers 25-30 lb loads to the padded hipbelt better than any frameless daypack.
- ✓The adjustable torso plus fixed frame fits a wide range without feeling vague.
- ✓Thick harness and hipbelt padding make it the comfort pick for all-day carries.
- ✓Trekking pole attachment and multiple organization pockets come standard.
- ✓Owners report years of heavy use with minimal wear on the 210D body.
- ✓The lifetime warranty applies as always.
Cons
- ✗At 2.6 lbs it's heavy for a daypack — the Talon does 90% of the job at 70% of the weight, as versus threads repeat endlessly.
- ✗The trampoline back bows the packbag, shrinking usable volume noticeably below the stated 24L.
- ✗The rigid frame makes it awkward as a travel/carry-on squish pack.
- ✗The mesh stands the load off your back, which scramblers say hurts balance on technical terrain.
- ✗Bottle pockets angle backward and are hard to reach one-handed.
- ✗The fixed top-zip layout offers less quick outside stash than the Talon's stretch pocket.
- ✗It runs warm everywhere except the back panel itself — the thick padding is a tradeoff.
- ✗Price plus weight make it easy to talk yourself into a full ultralight overnight pack instead.

Osprey Sirrus 24
The Sirrus is the women's-fit Stratos and the ventilated counterpart to the Tempest: a suspended AirSpeed mesh panel rather than contact foam, plus an included rain cover and a heavier 210D honeycomb shell over a 420D base. It is the day pack in Osprey's women's line for hot weather and long days.

Osprey Talon 22

Osprey Tempest 22
The Tempest is the women's-fit Talon and Osprey's technical daypack. The 2025 redesign moved the line to an AirScape ridged-foam backpanel that sits against the back rather than a suspended mesh, which keeps the load close and stable for scrambling at the cost of some airflow. It runs 11, 22 and 33 L.

Osprey Manta 24
The Manta is Osprey's hydration-specific hiking pack and ships with a 2.5 L Hydraulics LT reservoir, a magnetic bite-valve attachment on the sternum strap and a dedicated reservoir sleeve. It uses the same AirSpeed suspended mesh as the Stratos, so the price covers both the suspension and the bladder.

Osprey Sportlite 25
The Sportlite is Osprey's lightweight day-hiking line, refreshed for spring 2026 with a wider size run. At 27.2 oz for 25 L it is the lightest hiking daypack Osprey makes, using a 100D bird eye nylon and an AirScape foam panel rather than a frame and mesh. The 15, 20 and 22 L sizes use a fixed unisex harness; the 25 and 30 L add five inches of torso adjustment.
